"Schnittstelle lo hochfahren: " vs. ""Loopback Schnittstelle
hochfahren: " matches the english text differences between ""Bringing
up interface $i:" and "Bringing up loopback interface: ". Both
solutions are valid german and it's up to the personal preference of
the translator to select one.
But this still doesn't explain why you're getting two spaces after the
translated text. Please check what's in your message catalog with
